Yes I am aware by 900p and to answer your question, yes, it can fare well in 1080p in med-high settings so 900p will not be a problem.
You might need to turn down some settings for some CPU intensive titles.
I would not suggest this but there is a way that you can overclock the CPU by a tid bit since you have decent cooler if you flash your BIOS. Don't do it if this would be your first time OCing and the PSU is not that of good for OC.
